Exceed ABT Acetabular Cup Cementless System

Study Aim: To collect survivorship and clinical outcomes long-term data confirm-ing safety, performance and clinical benefits of the Exceed ABT ce-mentless cup when used in combination with ceramic and polyeth-ylene articulating liners

Objectives: Primary Objectives:

Clinical performance - as measured by clinical score data (HHS, WOMAC and Oxford Hip Score), radiographic as-sessments and survivorship which will be based on removal of the device.

Secondary Objectives:

Safety will be evaluated by monitoring incidence of adverse events. Length of study: 13 years (3 years enrollment plus 10 years follow-up): Post-operative follow-up visits at: 1, 3, 5, 7 and 10 years
